Pomabook.comLogo Design Contest

We're an online appointment scheduling tool, where businesses can schedule customer appointments via the web.

I'd like the logo to be able to look good in white & grey, but am open to using many colors.

Logo:
Pomabook.com is a new product that will be in the same product suite as Clockspot.com, so will have a very similar logo style and look/feel. Go to demo.clockspot.com to play around with Clockspot, and go to demo.pomabook.com (password is "12345" for all accounts) to play around with the alpha version of Pomabook.

We're looking for a logo that's simple, elegant, and a unique font of some sort. Facebook logo is a great example - it's just a stylized font:

Icon:
To the left of the logo I want an icon that represents Pomabook. Something that's recognizable on it's own. I'm a big fan of simple, 1 color logos, that can be inverted (shown on white background, or black background). Nike logo, Grooveshark.com logo and Apple are great examples. Other good examples: Twitter.com, Crowdspring.com, Zendesk.com, 37signals.com, uservoice.com. Ideally this icon + logo will be like Facebook or Twitter, where the font is unique, color neutral, invertible, simple, and instantly recognizable.

The final product MUST look good with the Pomabook.com application, and have a similar look and feel to Clockspot.com. Try logging in at demo.pomabook.com using password "12345", and look at the top left corner. This is where your newly designed logo will be placed. Make sure it looks good there!
